The Walking Dead's Andrew Lincoln and Norman Reedus Might Have the Best Bromance on TV (VIDEO)

The two men, who play Rick Grimes and Daryl Dixon on The Walking Dead, respectively, are as thick as thieves and completely at ease with each other.

On screen, if the two aren't busy saving the lives of people in Alexandria, they're killing walkers. And when the show returns next month, there will be "one episode that is very romantic," teased Reedus. Comparing their characters to classic movie duos, Lincoln joked the ep will be their version of Bill and Ted's Excellent Adventure, while Reedus said watching Butch Cassidy and the Sundance Kid helped them prepare for scenes.
